T0 all whom, it may concern.-

Be it known that I, FRANK P. PFLEGHAR, a citizen oi' the United States,and a resident of New Haven, in the county of New Haven and State oi'Connecticut, have invented a ncw and useful lmprovement in Windows, oi'which the following is a speciiication.

My invention relates to windows, and more particularly to windows foruse in connection with automobiles or wherever it is desirable to lift awindow-sash from its perpendicular position in use and store it in ahorizontal position overhead to be returned to its perpendicularposition for use at pleasure.

A practical embodiment of my invention is represented in theaccompanying drawings,

'in which Figure 1 is a partial view, in side elevation, of anautomobile, showing the window as it appears in use at the front of thelcarriage. Fig. 2 is an enlarged view in detail, showing a partialvertical longitudinal section with the sash partly raised. Fig. 3 is asimilar view showing the sash as it appears when nearing the raisedposition. Fig. 1 is a similar View showing the sash in its raisedposition. Fig. 5 is a View in detail, showing the transverse section inthe plane of the line 5 5 oi' Fig. 4. Fig. 6 is an enlarged view indetail, showing the sash in side elevation as it appears looking' at itfrom within the carriage. Fig. 7 is an edge view of the same; and Fig. 8is a view similar to Fig. 2, showing the application of a weight forbalancing the sash instead of the spring.

The window and its sash at the front of an automobile are commonl y madeheavy in order to stand the pressure upon them from high speed and jar,and my present invention is directed to providing means for readily7lifting and lowering this sash while sitting within the vehicle andwithout requiring undue strain upon the operator. which I have chosenfor illustrating my invention l utilize the hollow tubular posts whichsupport the carriage-top as a housing for the actuating-spring or weightfor counterbalancing the sash and also as a guideway along which thesashssupporting bearings are permitted to travel.

The glass part 'of the window is denoted by 1, and its frame by 2. Onthe side toward the occupant of the vehicle this frame is provided atits top with a handle 3 and at the bottom with a handle 1, the latterhaving attached To this end in the form.

thereto a rocking spindle 5, (see Fig. 2,) carrying a latch 6, which isadapted to engage with suitable keepers at the bottom and top of thefront post of the carriage-front to lock the sash in its normal orvertical position and in its lifted or horizontal position, as willhereinafter more particularly appear.- The window-frame 2 has attachedto its opposite sides bars 7 and 8, each carrying a pair or' swinginglinks, those carried by the bar 7 being denoted by 9 10 and thosecarried by the bar 8 being denoted by 11 12.' The links 9 and 11 are sopivoted to their respective bars that they will swing from a position inalinement with their respective bars, as shown in Fig. 7, inwardly at anangle to the bar, as shown in Fig. 2, while the links 10 and 12 are sopivoted to their respectivebars 7 and 8 that they will swing from aposition in alinement with the bars, as shown in Fig. 7, outwardly at anangle thereto, as shown in Fig. 2.

Each of the single links carries in its free swinging end alaterally-projecting spindle 13', on which is mounted a ball 111. (SeeFig 5.)

I prefer to construct the spindles 13 with an annular shoulder 15 attheir bases, one face of which shoulder may bear against the link andthe opposite may form a thrust-bearing for the ball 14.

The front posts of the carriage are denoted, respectively, by 16 and 17.They are connected at the lower portions by a cross-bar 18 and at thetop by an angle-bar19. Thecrossbar 18 has a socket 2O for the receptionof the catch 6 to hold the window in its vertical position for use, andthe depending flange of the angle-bar 19 has a socket 21 for holding thewindow in its horizontal elevated position out of use. The posts 16 and17 are continued along the rooi' of the carriage, on opposite sidesthereof, making a rounded turn at 22 and then continuing horizontally,as at 23, for a distance suiicient to accommodate the window to permitit to lie iiat against the roof, and in the event a weight is used, asshown in Fig. 4, to counterbalance the sash the tube forming the postand guideway along the top may be still further continued, forming arounded turn 24 and continuing on downwardly in vertical position, as at25. The tubular posts 16 and 17, as well as their extensions along thetop oi' the carriage, are provided on their inner Jfaces with a slit 26through their walls to accommodate the spindle 13 or the annularenlargement 15 there- IOO on, but of less diameter than the ball 14, sothat thelatter will be held within the tube as it travels along therein.

Along the top ot the carriage and on each side thereof there is formed aguide-plate 27, against which the top of the sash-frame 2 or of the sidepieces 7 and 8 engage as the sash is raised and lowered and while thelinks 9 and l1 are rocked at an angle to the sash. The weight of thewindow-sash, or a great portion thereof, is sustained by spiral springs28, one located in each of the posts 16 17 below the balls carried bythe links 10 and 12.

When the sash is in its lowered position, as shown in Fig. 1, thesesprings 28 are compressed and their tension is exerted in a direction tolift the sash. As the sash is lifted the spring gradually expands, asshown in Figs. 2, 3, 4, and its tension tending to lift thevsash becomesless as the weight of the sash is taken on the horizontal portion of itstubular guides. In lifting the sash the occupant ot the carriage simplyturns the handle 4 to unlock it at the bottom and then either lifts itby the handle 4 alone or, to make it easier, takes hold of the handle 3,as well as the handie 4, and slides it up with the greatest ease intothe position shown in Fig. 4 and there locks it by simply turning thehandle 4. In case the occupant wishes to lower the sash he may simplyturn the handle 4, unlock it from its elevated position, and lead itdown into its vertical position either by the handle 4 alone or by boththe handles 3 and 4. It will be observed that the two handles 3 and4'urnish an opportunity to lead the sash either in its upward movementor downward movement, and so render its motion easy. rIhe balls 14, usedas bearings, have no tendency whatever to cramp in their respectiveguides or bars, forming at all times antifriction bearings. Instead ofthe springs 28 weights 29 may be employed and when so used may belocated in the downward extension 25 at the rear of the front posts, andsuch weights may be connected by cords 30 with the spindles 13, whichcarry the ball-bearings.

Vhat I claim isH 1. The combination with a pair of continuous guides,parts of each being arranged at an angle to one another, of awindow-sash, links pivoted to the opposite edges of the window-sash,bearings carried by the links and engaged with the said continuousguides and means for counterbalancing the sash.

2. The combination with continuous tubular guides each having partsarranged at an angle to one another and each provided with alongitudinal slit through its wall, of a window-sash, bearings locatedwithin the tubular guides and connected through the slits with theopposite sides of the window-sash and springs housed in the tubularguides for counterbalancing the sash.

3. The combination with continuous tubular guides each having a portionextending in a vertical direction and a portion extending in ahorizontal direction and each providedl with a slit through its wall, ota .pair of swinging links pivoted to each of the opposite sides of thewindow-sash, spindles carried by the links and projecting through theslits in the tubular guides, balls mounted on the spindles within thetubular guides and springs located within the tubular guides below thelower balls for cou-nterbalancing the sash.

4. The combination with continuous tubular g'uides each' having portionsextending in a vertical direction and in a horizontal direction, ballsarranged to roll along within the guides and a window-sash attached atits opposite sides to said balls, of handles attached to the window-sashat its upper and lower parts for leading the sash in each ot twoopposite directions.

5. The combination with continuous tubular guides each having a portionextending in a vertical direction and a portion extending in ahorizontal direction, balls arranged to travel along the said tubularguides, a window-sash having its opposite sides connected with saidballs, a handle connected to the sash, a rocking catch under the controlof said handle, a frame connecting the said tubular guides at the footot the vertically-extending portions, a frame connecting the tubularguides at the top of the vertical portions, the said frames beingprovided with keepers for engaging the catch carried by the sash to lockthe sash in its vertical and horizontal positions.

6. The combination with continuous tubular guides each havingavertically-extending portion and a horizontally-extending portion,balls arranged to travel along within said tubular guides, awindow-sash, swinging links connecting the opposite sides of thewindowsash with said balls, guides located along said horizontalportions of the tubular guides for directing the top of the-window-sashas it lmoves into and out of its-horizontal position and means forcounterbalancing the sash.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two Witnesses, this 26th day of April, 1904.
